Hi Krzysztof,

Sorry for the confusion, we discussed [1] this patch in the last Series with Geert
and Linus W. We decided to Fixup (replace) the original patch with this and a
patch to the GPIO MMIO driver instead.  I pointed it out in the cover letter but
it may have not been clear.

I will reply to Bartosz's original mail too so he can understand the intent.
